summary

We know that there are always some diseases in our life. At this time, we need to go to the hospital in time for relevant examination. If we find the problem, we need to treat it as soon as possible. When you auscultate the breath sound, when the air passes through the trachea containing secretions, or through the narrow bronchus due to spasm or swelling, on the basis of the breath sound, I heard another kind of breath murmur, which is usually called rale. How is abnormal lung percussion caused? Now let me tell you something.

How is abnormal lung percussion caused?

The first one is dry rales, which are caused by trachea or bronchial stenosis or partial obstruction, air flow when inhaled or exhaled, like bronchial congestion and edema caused by some respiratory tract inflammation. When a dry rale occurs in the larger bronchus, it is called snoring.

Another is moist rales. When breathing, the air flows through the trachea or bronchus with a small amount of secretions, which makes the secretions form bubbles and burst rapidly. Big bubbles are the sounds of patients with bronchiectasis, pulmonary edema and other diseases. Small and medium bubbles are often seen in patients with bronchopneumonia and other diseases.

There is also the moist rale can appear in the whole lung, can also be limited to a certain part of the lung, inspiratory and expiratory can be heard, but deep inspiration is more obvious. You like common bronchitis and pneumonia, as well as tuberculosis and other diseases will appear this kind of sound.
